Pump station out of Tham Luang cave to rescue youth team with coach trapped in the cave from 23/6. – What is your group learning from the rescue team in Thailand?
– We recognize that this is a large scale campaign. very large, need experienced and knowledgeable people in the field of cave rescue. The Thai Army assigns searches at different stages and areas. The Navy is in charge of diving activities. Other forces look for other entrances to the mountain. There are thousands of people involved in this rescue operation.
The Thai government has promptly mobilized the world’s top cave divers. These are the first people to find children. More divers, British cave rescue workers arriving on July 5 along with additional equipment to rescue the team. Without these divers, the children might not have been found in time.
– What do you think about the potential for flooding, which causes people to be trapped in the cave?
– Since it has been thoroughly researched, the caves being exploited have very little risk of flooding during the time that we organize tours (January to August). The caves have many different entrances and are large in size. In the case of floods, these areas have separate drainage ways to avoid rising water levels.
We have seen floods in Khe Ry cave in Phong Nha – Ke Bang National Park. We do not organize exploration tours in this cave. But sometimes it causes some floods in Son Doong located downstream . Water from the Khe Ry cave runs from the Viet-Laos border, so it may not be rainy in Vietnam, but the rain in Laos still increases the amount of water in the Son Doong cave.
On the way up the prepared foot, to enter the shop Son Doong. If the water level is higher, we use suspension bridge assembled on top of Son Doong cave to cross the river with safety equipment. This allowed us to enter the Son Doong cave safely even when the rivers rose abnormally, sometimes up to 80m.
During the tour, if the water rises, it will also withdraw very quickly within 3 hours, down to 50m, allowing visitors to move in the cave without any danger. We do not organize exploration tours during the rainy season, from September to mid-November. If you follow these rules, there will be no flood events like in Thailand.
